Plug-in element for an optical plug-in connection

Abstract

The invention relates to a plug-in element ( 1 ) for an optical plug-in connection. Said element comprises a connector pin ( 2 ), which is held in a guide sleeve ( 4 ) by axial spring-loaded prestress, in such a way that it can be displaced in a limited manner along its longitudinal axis ( 3 ). The guide sleeve consists of at least two casing elements ( 5, 5 ′) that can be assembled along their longitudinal axes. Said casing elements significantly simplify the production and assembly, as no screw or adhesive connections are required.

 the guide sleeve ( 4 ) comprises at least two shell parts ( 5 ,  5 ′), which can be fitted together along the longitudinal center axis ( 3 ); and 
 adjacent shell parts have interengaging projections ( 7 ,  9 ) and recesses ( 8 ,  10 ) on their contact surfaces ( 6 ,  6 ′), at least some of the projections ( 7 ,  9 ) and recesses ( 8 ,  10 ) are studs and corresponding stud openings, which are formed conically in such away that the shell parts ( 5 ,  5 ′) are held together. 
 
   
   
     4. The connector part as claimed in  claim 1 , characterized in that the shell parts ( 5 ) are releasably held together by at least one cuff ( 11 ) surrounding them. 
   
   
     5. The connector part as claimed in  claim 1 , characterized in that a rib ( 14 ) is arranged on the inner side of at least one shell part said rib engages in a recess ( 15 ) in the outer casing of the connector pin ( 2 ) in such a way that its spring excursion is limited and it is held in a rotationally fixed manner. 
   
   
     6. A connector part ( 1 ) for an optical plug-in connection, with a connector housing ( 20 ) and at least one cylindrical connector pin ( 2 ), which is held in a guide sleeve ( 4 ) under axial spring prestress in such a way that it can be displaced in a limited manner in its longitudinal center axis ( 3 ), characterized in that:
 the guide sleeve ( 4 ) comprises at least two shell parts ( 5 ,  5 ′), which can be fitted together along the longitudinal center axis ( 3 ); and 
 the connector pin ( 2 ) or a component connected to the connector pin ( 2 ) has at least one run-on flank, which is inclined in relation to a plane running through the longitudinal center axis and which can be pressed against a run-on edge or run-on surface on the inner side of at least one shell part ( 5 ), under the action of the spring force, to determine the rotational position of the connector pin ( 2 ). 
 
   
   
     7. The connector part as claimed in  claim 1 , characterized in that the shell parts ( 5 ,  5 ′) form on the inner side an abutment ( 18 ) on which a helical compression spring ( 19 ) acting directly or indirectly on the connector pin ( 2 ) is supported. 
   
   
     8. The connector part as claimed in  claim 1 , characterized in that, to secure the guide sleeve ( 4 ) in the connector housing ( 20 ), there is arranged at least one resilient catch ( 25 ), which can engage behind a blocking shoulder ( 26 ) in the connector housing.
